[7u80] Request for approval for bulk integration of hs24.80-b05

[Alejandro E Murillo]

Requesting approval to integrate hs24.80-b05 into jdk7u80-b01.

A webrev is available at:

http://cr.openjdk.java.net/~amurillo/7u80/hs24.80-b05-jdk7u80-b01.webrev/

Pre-integration testing is in progress; the integration will proceed
only after SQE has analyzed the results and approved.

The fixes in the proposed integration are below.  All have undergone
nightly testing and are already in a jdk8 repository.
